python如何实现多行输入框_Python中的多行文本输入框

这是一个老问题,但目前以下是滚动多行文本输入一个很好的方法:

from tkinter import *

from tkinter.scrolledtext import ScrolledText

mainwin = Tk()

ScrolledText(mainwin, width=50, height=5).pack()

mainwin.mainloop()

以下程序演示了它的用法进一步与输入框的比较操作(python3):

from tkinter import *

from tkinter.scrolledtext import ScrolledText

mainwin = Tk()

Label(mainwin, text="An Entry Box:").grid(row=0, column=0)

ent = Entry(mainwin, width=70); ent.grid(row=0, column=1)

Button(mainwin, text="Print Entry", command=(lambda: print(ent.get()))).grid(row=0, column=2, sticky="EW")

Label(mainwin, text="ScrolledText Box:").grid(row=1, column=0)

st = ScrolledText(mainwin, height=5); st.grid(row=1, column=1)

Button(mainwin, text="Print Text", command=(lambda: print(st.get(1.0, END)))).grid(row=1, column=2, sticky="EW")

Button(mainwin, text="Exit", command=sys.exit).grid(row=2, column=0, columnspan=3, sticky="EW")

mainwin.mainloop()
